. Befm describing theme-hin@ is detail, itVv ma be mentioned thatthepresent machine is, or ,the most part, and exce tin only' thepressureor/and tensioning ro ler andassubstantially identical disclosedin my aforesaid copending application Serial No. 340,844 and referencemay made to the said-.r appl numerals employed in the presentspecification are,v soy numbers indicating li parts, so that the mannerinwhich the `present improvement is ap lied `to vthe prior machine may,if more detai ed information is desired, 'readily be l studied byreference to the rior application.

p Again referring to the rawing, the ma` chinecomprises side frames 11between which are' ivotally disposed upwardly upon `the brac ets 12andthe brackets 13, parsf'legs workfholder inthe form of a wor and 15` bthe' knuckles 17 and 18, thefwork table 16, egs 141and' 15 andsupporting brackets v12 and, 13 forming a @matura-permitting bodily to'andfro movement of the work holdingrtlpeblely, v

,v lbodily movement of the work table 16 is effected rearwardly bythercoiled spring 19, anchored at onel end in the bracket 12 and at theother end inthe leg 15, against which :Kring action movement may beeffected by e bar- 20,`having af wide rest 21 adapted to, body of theoperator.v To

' reventrearward tilting action of the work w L lding table, -I providea lockingmeans or frame, pivotally ,mounted in the bearings 23 on`tluayangularly disposed branch y24 of the e frame. This locking framecom rises the leverfmembers 2 5, whose ,inner en S26 are hollow and inwhich hollow portions 'are mountbe UV-shaped bracket ication for detailsofl the machine here thou ht limmaterial andtherefore not set forth. f nfact, the reference far as possible, identical withv prior application,like l ed spring pressed plungers 27. These levers, two in number,provided adjacent each side vof the frame 11, are caused to be operatedin unison by the cross bar 28. It will be observed that rearwardmovement of the work table 16 is prevented by the plungers 27 engagingthe legs 15. To forwardly lock the table, the cross bar 28 is pulledupwardly in a' clockwise direction and when moved past the dead-center,as shown, the work holding table is locked against movement rearwardly.-The spring pressed plunger 27 also servesV to resilientl-y hold the worktable in itsv locked position with the work yieldingly held in position.

At the leading or forwardend of the work holding ltable 16 thereismounted a feed roller 3l. Below this, there is mounted a feed or/andpressure or/and tensioning roller 133.v .'Thebearings vfor the latterare carried at'the upper ends of oscillatable arms 134 the lower endsYof which are afiixed in bearings 135 on the work holding frame. Theposition of each of the arms 134 is adjustable by 'movement of arod 136one end of which is pivotally anchored in the arm 134, and the other endofwhich is Ithreaded and carried in a 137.l A manually adjustable nut138isA ositioned between the legs ofthe U-shaped racket, and .rotationthereof moves the rod 136 and with it the arm 134 In consequence,besidesthe give oryieldabily ity of-theentire work holdingframe againstthe spring pressed plungers 27, the roller 133 is itself yieldable, sothatv pressure exerted thereby on the pelt is not critical. Foraccomplishing the rapidly alternating brushing and ironing operationsheretofore set forth, I provide a drum 40 positioned at the upper partof the frame, within the bearings 39, which drum is provided Iwithspiders 41 having end shafts or trunnions 42 arranged to be disposedwithin the bearings 39 for rotation. The peripheral surface of the drumis provided with alternately spaced ironingplates 43-and brushes 44arranged in contiguous relationship.l Interiorly of the drum andadjacent the ironing plates 43, there are yprovided heating units 45.

Disposedupwardly of the drum 40, there isj provided thev arcuatelyformed hood 54.

andthe roller'133.- In this manner, the'presthe bearings 62 in theextremeend of the hood. The feed roller 61 as thus provided invasivaA isarranged inthe operationof themachine to be in contactin relationywithfthe feed roller 3l, mounte ,upon the work holdin' table previouslydescribed.4 The hood is pre -f erably made of fexible material'so as tovbe resilient `and therefore adjustable'to vary-1 ing thicknesses 'ofthefur.' f

The apparatus is provided with a stub shaft pinion or gear 63 drivenbythe electric m0- tor, not shown, through themedium ofa gear traincontained ivithinlthe cover 65.` MeshingA with the pinion 63, there isprovided` a `gear 67to which is aixedva pinion 68 fixed to an' end ofthe feed roller 31. "The pinion 684 is adapted to mesh with a pinion69-on the feed:`

parts are in operative ar-` roller 61 when the rangement.

n the shaft of feed roller`31, and rotating with gears 67 `and 68, there4is fixed a sprocket near 141.

ingv the pressure andftensioning roller 1,33.`

Thesesprocket gears are operativelyconnected by a chain 143.v The chainand s rocket mechanism causes the tensioni-ng rol er 133A to berotatedwhen" the feed roller `31 is'rotat` ed, and both are rotatedinthe same direction as theyshouldbe. f Asis evident from Fig.v 1," theaxes of rollers`"31, 133, andbearing 1315, are so related thatadjustment of lroller 133 toward or fromthedrum D slight-j ly alters thecenter tocenter spacing ofrollers 31 and`133, and therefore'of sprockets`141 and 142, and, this'slight variation is readily permitted by slackness in the chain 1,43.`

The peripheral speed of the pressure roller 133 is preferablymade'gretjer than that of the feedroller 31 in order thaltthefpelt mayloe placedin tension 'and therefore pressed against the periphery ofthedrum. VThe desired increase in peripheral speed may be obtained byeither, or as in this case by both, of

two expedients, first, increasing `the diameter of the roller 133relative to thatV ofthe feed 'roller 31, and secondly, increasing thediameter of the sprocket 141 relative to that of the sprocket ""ln theparticular machine here in question, the peripheral speed of thetensioning roller 133 is made about three times as `great asthat ofthefeed roller 31,

but it will be understood thatthe ditference'in f peripheral speed maybe variedV over a wide with this recited constructions wiaA be, seenthat when thework table 16 is moved'to the position shown, the gear 67will move into meshing engagement with the pinion 63 and the gea.' 68with the pinion 69` so that operation of the motor will result inrotating rin unison the feeding and pressure rollers 31 and 61,respectively, andthe tensioning roller 33. The drum 40 is also rotatedby the gear train contained within the cover casing 65,-the said Y drum40 being rotated, asshownby the arrows, in the directionof feedingmovement of n Another sprocket' gear 142 is mounted on the end of theshaftzjcarry the workfed` by lthe feeding' and pressure peripheral speedofthe drum 40is made very much greater than the peripheral speedsfnii ithe feeding and pressure or/and tension rollrollers; To accomplish thedesired ends, the

Below the workta'ble 16 there isiprovided a work guiding-apron' 1,disposed below the drum 40 I and the tensionroller 33; fand this is heldin position upon the rod 72 andthe upper edge ofi a dust hopper 73,7which h0p .V Per is connected through a duct 74 to a suc-`` Vtion fan,not shown.`

l For practicing myiinvention in connection with the apparatus justdescribed, a fur plece or pelt, such as`10,is spread-upon the work table16 when the latter is in retracted` position, the operator spreading4the same upon this table and then bearing aga-inst the lrest 21'untilthe `table hasbeen moved for i i ward] tocause the gears and pinions 68,69, 63 an 67 to in mesh. The locking frame is then brought to thelocking position wby lifteffected by pressureof the operators bodv this.positionfand the motor placed in Arota.-

tion,one end of the pelt will be picked upfby v the feed roller 31 untilit is squeezed between the said roller and the feed roller 61. At thispoint, the edge of the pelt is engaged by the rapidly rotating drum4.0.l 'The pelt is'r then ing the bar 28 upwardly. If desired, thelocki.4ing frame need not be used,operation being l against thebar 21..`llVith the apparatus .in

fed downwardly overthe feed roller31 and i soon reaches thetensioningroller 133-Which keeps the" pelt in direct contact with theidrum tweenthe rollers 31and133 to vbe pressed and which causes the portion ofthepelt beagainst the surface of the-drumdhe pelttakf` Y ing the naturalcurvaturelofthedrum, or,

if it departs. from the natural curvature, does so in such1 a manner asto ff automaticallly obtain the desired pressure of the fur against thedrum. In actual operation, this results in a uniform pressure, and;infact seems to permit the peltto fiutter or vibrate veryslightly so asto take the `best natural pressure for the successive brushingandironing`steps,-and it is found that skinsA treated in the presentmachine are A given uniformly excellent finish and luster. The rotationof the drum is such that its peripheral speed is far Vgreater than thatof the linear movement of the pelt permitted Vby the ,feed roller 31 andthe feed roller 61,`so that tinued for the full length of the pelt 10and this then drops upon the apron`71 and is gath-v' .eredbytheoperator'in completely treated pressure will exist during the entiretreatl ment o f the fur. In consequenceof `these ad- P 2 vantages,different kinds of fur mayt be fedv condition.

The construction and operation of my imrovement in fur treatin machineswill" it cs believed, be apparent rom the fore omg description thereof.The. present macine,

vwhile retainingall of the advantages of my' prior machine, has theadditional advanta of not being critical in the adjustment of t e jpressure roll and. in permitting the `fur'` to assume an arcuate shapebest adapted lto lit the brushing and'ironing drum, and in allowingv forvariation in the position of the skin ac.

'cording to its thickness and texture and length of hair, and accordingto whether it is in contact with the brushing or ironing portions of thedrumso that a more uniform through the machine in rapid succession,without bothering to make adiustments when changing the kind of fur. anduniformlvexcellent results are nevertheless obtained.
